Which of these 23 links backs up the claim that "people only respond to violence," or, paraphrasing, non-violent resistance is ineffective?
I tried to skim a couple, but the synopsis on one was simply a recounting of black power tactics from the 70s, and another was a wiki page about the radical flank effect, which actually referenced the book I linked to support the claim that having a violent radical flank appeared to have no positive effect. Other references sometimes found a positive effect, but I can't really compare the merits of the sources.
Honestly, having a pile of obscure links to whip out in favor of political violence is, at a minimum, odd.
I am willing to deal with a cheesy lisp if you play a good game of Terraforming Mars or Gaia Project.
